E. w. SMITH EDGE SETTING MACHINE Original Filed May 17, 1940 A/Tmq f The clamping device consists of a shoulder 60 which extends from one side of the enlarged tool v carrier head 56 where it is adapted to engage a relatively large area'of the side I92 of the bur. nishing tool 58. ii A relatively large area of the opposite side 164 of the tool 53 is engaged by the roughened side ofa plate. 52. which isfastened on the tool carrier head by a screw 64. The'inner face of the plate 62, which is adjacent to the tool carrier head 55, is recessed from a point a slight distance beyond the headiadjacent to the tool to a rib E5 on the end of the plate.

the holder, a burnishing tool having an end face designed for engagement with the work and having also a pair of oppositely disposed side faces, said carrier having a shoulder which is rigid with relation to said registering portion of the carrier and is adapted to be engaged by one of said side faces of the burnishing tool, a plate 7 adapted to engage the opposite side face of the to clamp the tool to the carrier andthereby pre When the screw 6 is tightened, :the' plate will I fulcrum about the rib 65, causing the roughened part of the plate 62 to press the tool 58 against the shoulder 68, thereby clamping theteol be-' tween them so that there can be no relative .movement between the tool and the tool carrier when these members are oscillated. The arrangementof the clamping faces of the tool in intersecting relation to its vibratory path {of -movement tends to efiset 'anydanger of the tool being loosened in its clamp byd'e'as on of the sud Y den and frequent reversal of movement.
